This grinder is prettt run of the mill. Simple acrylic 2 piece that gets the job done.
Very basic grinder
Full disclosure I received this as a free accessory to a vape purchase. this thing is okay for a very small jobs. As it doesn't have a screen you just put the herb in and grind it and then get it out. There's no chamber below for it to fall into.. can't see anyone using this as anything but a portable device.
Basic cheap grinder
There is no catcher on my grinder so it technically works (barely) at grinding my flower, but then I have to flip it over to store it in the chamber.
